2 Connecting to the I/O Interface System Components Connecting to the I/O Interface The HAWK MV-4000 has a digital I/O interface with 7 optically isolated signals. There are three digital outputs and four digital inputs. Outputs Output Signals: • Output 1 • Output 2 • Output 3 (External Strobe when Enabled) • Output Common The outputs support sinking (NPN) configurations only and operate at up to 24V nominal. All three outputs are configurable for general-purpose use, but when External Strobe is enabled in the software, Output 3 becomes dedicated to that purpose.
When the HAWK MV-4000 is used with the QX-1 interface device, or with any of the NERLITE Smart Series lighting cables, the Strobe Output signal from the camera is automatically connected to strobe trigger input on the Smart Series light. Inputs Input Signals: • Trigger (Sensor) • Input 1 • Input 2 • Input 3 • Input Common The inputs support sinking (NPN) and sourcing (PNP) configurations and can receive 11-24V. Note that sinking (NPN) or sourcing (PNP) for inputs cannot be mixed in a system because the Input Common is shared by all Inputs. One input is dedicated as the camera trigger (sensor). The other three are configurable general-purpose inputs.
When the HAWK MV-4000 is used with the QX-1 interface device and photo sensor, the trigger signal is automatically connected to the correct input channel. HAWK MV-4000 Smart Camera Guide 2-17
